Thimbleby's Tower
Thimbleby's Tower, formerly known as Wolf's Tower, is a structure in the city walls of Chester, Cheshire, England. It stands on the eastern section of the walls, between Eastgate and Newgate. The tower is recorded in the National Heritage List for England as a designated Grade I listed building. History The tower probably dates originally from the 13th century. It was partly demolished in the siege of Chester in 1644–46 during the Civil War. Between 1702 and 1708 the whole of the city walls was converted into a raised walkway and it is likely that the tower was modified as part of this process. Repairs were carried out to it in 1879. It was further altered in 1994–95 for Chester City Council by Peter de Figuerdo. Architecture Thimbleby's Tower is constructed in coursed red sandstone rubble. Its plan is semi-octagonal, and it appears to be the outer part of a drum tower without its upper storeys. The lower chamber contains three loops (unglazed slit w ...

Chester City Walls
Chester city walls consist of a defensive structure built to protect the city of Chester in Cheshire, England. Their construction was started by the Roman Britain, Romans when they established the Castra, fortress of Deva Victrix between 70 and 80 [CE]. It originated with a rampart of earth and turf surmounted by a wooden palisade. From about 100 CE they were reconstructed using sandstone, but were not completed until over 100 years later. Following the Roman occupation nothing is known about the condition of the walls until Æthelflæd refounded Chester as a burgh in 907. The defences were improved, although the precise nature of the improvement is not known. After the Norman conquest of England, Norman conquest, the walls were extended to the west and the south to form a complete circuit of the Middle Ages, medieval city. The circuit was probably complete by the middle of the 12th century. Maintenance of the structure of the walls was an ongoing concer ...

Springer (architecture)
In architecture, a springer (sometimes springing) is the lowest voussoir (wedge-shaped structural element) on each side of an arch. Since it is the bottom-most element of the arch, it is where the arch support terminates at the respond. It rests on the impost or pier of the arch, that is, the topmost part of the abutment An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls ..., from which the arch arises. Usually, the springer is located at the bottom of an arch curve. The "delayed" springing (when the curvature starts noticeably above the support) is a trait of a stilted arch, common in Romanesque and Gothic architecture.

Buildings And Structures In Chester
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gable
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The term gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roof do not have a gable (for example hip roofs do not). One common type of roof with gables, the 'gable roof', is named after its prominent gables. A parapet made of a series of curves (shaped gable, see also Dutch gable) or horizontal steps (crow-stepped gable) may hide the diagonal lines of the roof. Gable ends of more recent buildings are often treated in the same way as the Classic pediment form. But unlike Classical structures, which operate through post and lintel, trabeation, the gable ends of many buildings are actually bearing-wall structures. Gable style is also used in the design of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate ester, carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, toughness, tough materials, and some grades are optically transparent. They are easily worked, injection molding, molded, and thermoforming, thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code, resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confer rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate ester, carbonate groups (−O−( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapet
A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of the wall, sometimes with a coping at the top and corbel below. *Embattled parapets may be panelled, but are pierced, if not ...

Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the Keystone (architecture), keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or Circular segment, segmental head, which supports the voussoirs until the ring of the whole arch is completed. The Mycenaean Greece, Mycenaeans (ca. 18th century BC, 1800–1050s BC, 1050 BC) were known for their Tholos (architecture), tholos tombs, also called beehive tombs, which were underground structures with conical vaults. This type of vault is one of the earliest evidences of curved brick architecture without the use of ston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubble
Rubble is broken stone, of irregular size, shape and texture; undressed especially as a filling-in. Rubble naturally found in the soil is known also as 'brash' (compare cornbrash)."Rubble" def. 2., "Brash n. 2. def. 1. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) © Oxford University Press 2009 Where present, it becomes more noticeable when the land is ploughed or worked. Building " Rubble-work" is a name applied to several types of masonry. One kind, where the stones are loosely thrown together in a wall between boards and grouted with mortar almost like concrete, is called in Italian "muraglia di getto" and in French "bocage". In Pakistan, walls made of rubble and concrete, cast in a formwork, are called 'situ', which probably derives from Sanskrit (similar to the Latin 'in situ' meaning 'made on the spot'). Work executed with more or less large stones put together without any attempt at courses is called rubble walling. Where similar work is laid in ...

Chester
Chester is a cathedral city in Cheshire, England, on the River Dee, Wales, River Dee, close to the England–Wales border. With a built-up area population of 92,760 in 2021, it is the most populous settlement in the borough of Cheshire West and Chester. It is also the historic county town of Cheshire and the List of Cheshire settlements by population, second-largest settlement in Cheshire after Warrington.

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
